• Think in funnels, cohorts, and behavioral data.
• Optimize for measurable outcomes over roadmap output.
• Value rapid learning, iteration, and continuous optimization.
• Deeply comfortable using data to identify opportunities, validate hypotheses, and make decisions.

• Understand the opportunities and constraints of mobile customer experiences and can simplify complex workflows into intuitive user journeys across devices.
• Actively leverage AI tools to accelerate workflows, improve decision-making, and increase team efficiency.
• Excited about how AI can enhance personalization, experimentation, and customer growth.
